Authentication Using Three Phase Password

Authentication is necessary in any system as it provides more security to that system. Current authentication techniques such as textual passwords, biometrics and graphical passwords have several limitations and disadvantages. To overcome the drawbacks of these techniques, we propose a new improved technique is used called the Three-Phase Password. Three Phase password is a multifactor authentication scheme. In this technique, we implement the password as a combination of textual password, graphical password and the co-ordinate position. Three-Phase Password is an advanced authentication scheme and is more secure than other authentication techniques. This paper presents the working and implementation of Three-Phase Password and also shows how this technique is more secure than the existing authentication scheme.
